C36 M104 idle noise
I have read a lot of thread about the "diesel" noise these motors make. My car definitely has it and am trying to get a feel if my engine falls within the norm or not. I am running 10/40 royal purple oil in the engine. The diesel noise only stays till about 1700-1800 rpm at which point it sounds normal. I have read some threads saying this is where the cam adjuster starts to kick in. I took a video of the car at idle earlier to see what you all think.
Thanks in advance for any feedback- Cory
